              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had several waves of high clouds tonight, sometimes troublesome for short periods but we kept struggling through.  A nice new filter for exoplanet transit observations was delivered and installed in ARCTIC.  Everything worked well.
